Introduction

In this demonstration, MAEviz will be used to perform a damage analysis on some buried pipelines in Shelby County Tennessee. It is assumed that the user has already worked through the MAEviz Introduction and Tutorial and is familiar with the basic functions of MAEviz that can be found in the Building and Bridge Damage Tutorials. If not, then it is suggested that the user do this first before continuing with this tutorial. The sections that follow will take the user through the ingestion process (to get some pipeline data into MAEviz) and then run a sample analysis using the Buried Pipeline Sample Inventory for Shelby County Tennessee that can be found in the MAEviz Public Repository.

Data

Pipeline data can come in many formats; however, for use in MAEviz, the data must be in shapefile format and contain at a minimum, the pipe material type (e.g. cast-iron, pvc) and the diameter. Additional attributes such as joint type and soil type may be required, depending on which fragilities the user wants to assign to the pipeline data. A column for joint type and soil data are required to exist (even if they contain no information) because the schema for this type requires those columns to be present. If your dataset does not contain them, then they will need to be added before ingesting the pipeline dataset into MAEviz. Another useful field is the length field since this can be used to determine the number of repairs based on the repair rate. Below is a list of the fields required to be present in the dataset:

• pipetype - the pipe material
• jointtype - the type of joint
• diameter - the diameter of the pipe
• length - the length of the pipe section
• soiltype - the type of soil that the pipe is in.
